Cascaded Logic Gates with Printed Electrochemical Memristors

Abstract

Electrochemical‐based memristors are highly attractive that are capable of nonvolatile analog tuning, long‐term state stability, low power consumption, device scalability, and fast switching speeds. Through the combination of film deposition techniques, i.e., vapor phase polymerization and screen printing, fabrication of a poly(4‐(6‐hexyl)‐4H‐dithieno[3,2‐b:2′,3′‐d]pyrrole) (p6DTP)‐based synaptic‐emulating three‐terminal memristor is designed. Through voltage‐driven pulse programming, and square waves with an amplitude of 100 mV and duration of 100 msec, the device exhibits a power consumption of 1 pJmm−2 per synaptic event. By analyzing the fundamental operational trends of the p6DTP‐based device, simple and advanced integrated applications can be demonstrated along with synaptic‐like responses. This effort is the first presentation of the vapor phase polymerization technique for any dithienopyrrole‐based monomers, along with the physical implementation of any memristive system as an advanced logical circuit, demonstrated here as a cascaded combinational logic gate.

Offset boosting in a memristive hyperchaotic system

“…Over the recent years, as a nonlinear two-terminal component with the intrinsic memory effort that connects electric charge with magnetic flux [1], the memristor has aroused considerable interest in various applications such as logic gates [2,3], reservoir computing [4,5], neuromorphic computing [6,7]. In particular, the particular advantages of this device offer additional flexibility for generating chaos [8,9], hyperchaos [10,11] and complex dynamics [12,13].…”
